> After upgrading to Ambari 2.0 (from 1.7) it wants to manage Kerberos but it doesn't seem
to have the capability to just use the existing keytabs as we have historically done - it
wants to redeploy them from an MIT KDC, which would obviously mess up my already deployed
cluster which is running on FreeIPA (which includes an MIT KDC in each IPA server but isn't
supported to be managed via kadmin interface).
> There doesn't seem to be an obvious way of getting Ambari to re-enable or recognize that
kerberos is deployed and the services are kerberized. The current configurations do seem to
still be intact with the kerberos config settings but Ambari does not recognize that Kerberos
is deployed and I'm concerned this is going to eventually mess up my existing cluster or deploy
new services without Kerberos.
